IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 20,269, dated May 18, 1858.

To all whom it may concern:

Be it known that I, JOHN M. HALL, of Warrenton, in the county of \Varren and State of Georgia, have invented a new and Improved Flow; and I do hereby declare that the following is a full and exaetdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, like letters referring to like parts.

The nature of my invention consists in forming a plow which, by the combination of the parts, shall produce a plow that will be capable of performing all the work ever required either as a common plow, subsoil, opening, sweep, or hillside plow, or any two of them combined, without the necessity of having separate frames or stocks, by simply arranging the parts as the nature of the work requires.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction.

I construct my plow-frame with a beam of wood, which is mortiscd in three places to re eeive the colter-beam, the share, and the sword or cutter. These are kept in their several places by the use of keys or wedges. At the hind end of the beam is framed a post to which the handles are attached by the use of a cross-bar or rod, and the hook for the hillside or swivel plow is also attached to the post, the handles being attached to the beam forward of the colter or share, and by the use of an adjustable colter beam or shank having one or more adj nstable points of steel, as the plow may be required for use either as a common turning or subsoil plow, the upper points being adjustable by means of bolts to the colter-beam. This beam is made of iron, and has on the front a deep channel or groove to receive the share with the moldboards, which are made of cast or wrought metal. The back of the share has a flange which fits into-the channel of the eolter-beam sword edged with steel is also made use of, I

placed so as to bring the edge immediately in line with the edge of the share.

The double mold-boardplow is made the same as the single, with the exception that the points out on both sides, and has moldboards on both sides. It is also a subsoil-plow by using the extra point, as in the single moldboard.

At the rear end of the plowbeam is attached an iron frame bolted to the beam. (This frame can be removed, excepting when using the plow as a hillside-plow.) This frame forms the standard for the mold-board of the hillside-plow, which is two in one. A book fastened to the center post of the handles by a staple, and changing to either side of the beam, as may be desired, enters the back part of the mold-board and holds it fast on either side, as wanted. In connection with this plow I also make use of the colter-beam and cutter, as shown in Fig. 2. To make this a subsoil as well as hillside plow, I use the extra point. The sweep and opening plows are used without the eolter-beam or cutter.

Figure 1 represents the plow as a single mold-board plow and subsoilplow. A, the standard for the hillside-plow; B, the colterbeam; O, the extra point which converts this into a subsoil-plow; D, the cutter or sword, and I the mold-board and share;

Fig. 2 represents the same as a hillside or swivel plow. A, the standards; B, the colterbeam with double cutting-point; D, the cutter; I, the mold-board; K, the hook to fasten the mold-board in its place.

Fig. 3 represents the same asa double moldboard plow. A, the standard for the hillside -plow; B, the colterbeam with its permanent double cutting-point; D, the cutter or sword; I I, the mold-boards and share.

Fig. 4 represents a sweep-plow.

Fig. 5 represents a front View of the double mold-boards of the plow. B, the colter-beam; (J, the double cutting-point; I I, the moldboards and edge of share.

Fig. 6 represents an opening-plow.

Fig. 7 represents the colter-beam and the double cutting-points with the channel or groove'in the beam. B, the eolter-beam with its movable parts, as herein described, whereby it is readily adapted to properly receive in turn the several parts employed for performing the various modes ofeultivation specified.
